When embarking on a solar installation project with Better Earth, one of the critical components to consider is your home's main service panel (MSP). Sometimes, to safely and efficiently integrate a solar system, an upgrade to this panel might be necessary. Here's a detailed exploration of the process, designed for those who want to understand every aspect:
Determining the Need for a Main Service Panel Upgrade (MPU)
Post-Site Survey Evaluation: After conducting a site survey, our team will assess if your current main service panel can handle the additional load from the solar system. If it's determined that an upgrade is needed, you will be informed promptly.
Avoidance Strategy: Our design team works diligently to avoid MPUs where possible due to the additional costs and time they add to the project. Solutions like installing a subpanel or derating the system might be explored as alternatives.
Necessity of MPU: Certain types of panels, like Zinsco, Sylvania, or Federal Pacific, are outdated or known for issues, making an MPU mandatory for safety and compliance reasons.
The MPU Process
Application to Utility: If an MPU is deemed necessary, we'll start by submitting an application or request to your utility company. This step is to verify if the current location of your main panel is suitable or if relocation is required, which could impact both cost and timeline.
Panel Size Considerations: Typically, we aim to install a 225/200 amp panel, but in some cases, a 125 amp or 100 amp panel might be sufficient, based on your home's electrical demand and solar system size.
Installation Planning: We plan to schedule the solar installation as closely as possible to the MPU to minimize disruption and ensure efficiency.
Subcontractor Involvement: In some instances, Better Earth might engage a subcontractor specialized in electrical panel upgrades to perform this work, ensuring high standards of safety and quality.
Execution of the MPU
Preparation: Before the upgrade, we'll coordinate with you to ensure minimal inconvenience. If the MPU requires disconnecting your electricity, you'll be notified well in advance, typically for a few hours.
Installation: The dimensions of the work area will depend on the size of the new panel. Our team or subcontractor will work meticulously to install the new panel, adhering to all local electrical codes and standards.
Alternative Solutions: If an alternative to a full MPU is viable (like a subpanel), we ensure this is approved through local codes and an engineering review to maintain compliance and safety.
Frequently Asked Questions (FAQ)
Q: How will I know if I need a main service panel upgrade?
A: After the site survey, Better Earth will inform you if an MPU is necessary based on the electrical capacity and condition of your existing panel.
Q: Why does Better Earth try to avoid MPUs?
A: MPUs can increase both the cost and duration of your solar project. We look for alternatives to keep your project efficient and cost-effective.
Q: What happens if my panel type requires an MPU?
A: Panels like Zinsco, Sylvania, or Federal Pacific often require an upgrade due to safety concerns or outdated technology. We'll proceed with an MPU in these cases.
Q: Can the MPU be done at the same time as the solar installation?
A: We aim to schedule the solar installation right after the MPU to streamline the process, but sometimes, utility approval or logistical reasons might delay this.
Q: Will there be a power outage during the MPU?
A: Yes, in some cases, a brief power outage might be necessary. You will be informed in advance to prepare for this.
Q: How long does an MPU typically take?
A: The actual upgrade might take a day or less, but the entire process, including utility approval, can extend the project timeline by weeks.
Q: What if moving the main panel is required?
A: If relocation is needed, this will be communicated, and the additional costs and time will be discussed. We'll work to minimize any inconvenience.
Q: Will Better Earth handle the MPU directly?
A: While we manage the process, in some cases, we might use a trusted subcontractor to perform the physical upgrade, ensuring professional standards are met.
Q: What are the benefits of upgrading my main service panel?
A: Beyond solar integration, an upgraded panel can increase your home's electrical capacity, potentially improving its value and accommodating future electrical needs.
Q: Can I opt out of an MPU if it's recommended?
A: If an MPU is necessary for safety or compliance, opting out isn't advisable. However, we'll explore all possible alternatives before recommending an upgrade.
Q: How do I prepare for the MPU?
A: Clear the area around your electrical panel, ensure easy access, and prepare for a potential brief power outage by securing any sensitive electronics or medical equipment.
Q: What if I have concerns about the MPU process?
A: We encourage you to voice any concerns or questions to your Better Earth representative. Our goal is to ensure you're comfortable with every step of your solar journey.
